I've noticed this too, this happens when you do a "broad sweep" copy that includes the last line of text, right? (By "broad sweep" I mean, that you click the mouse and just highlight the text until all is selected, not stopping on the last letter).
Now, when you stop on the last letter, so that it is still highlighted, but don't select any more, it should just copy that line of text.
That would explain why the problem was intermittant. Damn my tendency to paint with a broad brush!
Thanks, and thanks to jar too. I've been away for a while and I forgot how to use the software.
